Title: Alum.-magnesium-silicon based alum. alloy excellent in extrudability
Inventor: YANAGAWA MASAHIRO
IPC: C22C21/06
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To improve the extrudability of an Al-Mg-Si based Al alloy by provid ing an Al-Mg-Si based Al alloy in which a crystallized substance consisting of Al-Fe-Si compound is α-phase and a precipitate consisting of Mg2 Si and a precipitate consisting of Si oxide are not present practically. SOLUTION: In an as-crystallized state at the time of casting and solidification, β-AlFeSi is formed. Because β-phase is a brittle compound, picking-up is caused at the time of extrusion and seizure resistance is deteriorated. By performing soaking treatment at prescribed temp. for prescribed time, the β-phase is transformed into α-phase. Because an Mg2 Si precipitate is a brittle compound and causes picking-up at the time of extrusion, hardening is applied from the prescribed temp. to reduce it. As a precipitate consisting of Si oxide causes picking-up and it is produced when soaked at high temp. and then cooled slowly, hardening is done, e.g., by water cooling to make it disappear. By this method, the occurrence of picking-up at the time of extrusion can be prevented.

Title: Optical isolator
Inventor: MAKIO SATOSHI
IPC: G02B27/28
Filed: 1987-07-16
Abstract: PURPOSE:To obtain an optical isolator without generating the deviation of an axis and easy to use, by setting an angle on one side and the angle on the other side at prescribed values in a case where the angle made by the normal of an incident end face in a polarizer and that of an incident side end face in a Faraday rotor is projected on a specific plane including the optical axis of incident light. CONSTITUTION:Assuming that light is made incident on the normal on the end face of a substance 4 with thickness (l) and a refractive index (n) at a certain angle theta, the optical axis of emitted light is set in parallel with that of the incident light, however, parallel displacement is performed, and the former is deviated by (b) from the latter. The above deviation quantity can be found by a Snell's law. By setting only the angle theta2 (theta, theta1, and theta3 are assumed at >=0.5 deg., theta2 at >=-0.5 deg.) of the normal of the Faraday rotor FR is set at a code opposite to that of the normal of each end face of the polarizer P1 and an optical detector P2, the deviation quantity (b2) at that time can be obtained by a prescribed equation, but, as a whole, the deviation of the axis can be reduced by the Faraday rotor FR remarkably.

Filed: 1987-07-15
Abstract: PURPOSE:To reduce the cost of the whole device by providing plural photosensor pats containing an LED and one end of an optical fiber, and allowing the other end of plural optical fibers to oppose to one photodetector. CONSTITUTION:Plural photosensor parts are constituted of LEDs 1, 2 and 3, and one end of optical fibers 6, 7 and 8.

IPC: H03K19/0952
Filed: 1991-07-18
Abstract: PURPOSE:To reduce the difference between drain currents flowing between the sources and drains of field effect transistors connected to pads for power supply by changing the distances between the sources and gates of the transistors by means of the connecting positions of the transistors so that the distances can become longer as going toward the pads for power supply. CONSTITUTION:A plurality of field effect transistors 22b and 24b connected to wiring electrodes 5 and 6 which in turn are connected to pads 8a and 8b for power supply are incorporated in a semiconductor device provided with a logic circuit. The distance between the gate and source of the transistor 22b which is connected to the electrodes 5 and 6 at positions nearer to the pads 8a and 8b is made longer than that of the transistor 24b connected to the electrodes 5 and 6 at positions farther from the pads 8a and 8b. Therefore, even when a plurality of field effect transistors 22b and 24b are connected to the same wiring electrodes 5 and 6, the difference between drain currents flowing to the sources and drains of the transistors 22b and 24b becomes smaller and the fluctuation of the operating voltage can be suppressed.

Title: Turn-off circuit for device having self turn-off function
Inventor: IWAMOTO HIDEO
IPC: H02M1/06
Filed: 1980-12-16
Abstract: PURPOSE:To prevent a specific device from being overloaded, by progressing the turn-off of a device with slower turn-off smong a plurality of turn-off devices connected in parallel. CONSTITUTION:When a turn off time of a GTO2 is shorter than of a GOT1, the GTO2 starts the restoration of a voltage block capability at a time t2 and an anode current iA2 starts decreasing. On the other hand, the turn-off time of the GTO1 is longer and still in on-state and it does not restore the voltage block capability. When the current iA2 starts decreasing, a current flowing to the secondary winding 5 of a transformer 3 is smaller than that flowing to a primary winding 4. Thus, a voltage with the polarity as shown in Figure is generated on each winding and the current flows in the path of ternary winding 11  transistor 17  cathode/gate of GTO1 ternary winding 11, the gate reverse current iG1 of the GTO1 is increased and the turn-off time of the GTO1 is quickened.

Abstract: PURPOSE:To prevent generation of failure or deterioration in characteristics by a method wherein, after the wafer obtained by slicing the semiconductor single crystal of the specific oxygen concentration is subjected to internal gettering treatment, a region having the prescribed conductive type and impurity concentration is formed by diffusing impurities. CONSTITUTION:A wafer 1 of about 300mum in thickness is formed by slicing silicon crystal of oxygen concentration of 5X107/cm3 formed using an MC2 method, and the wafer is annealed in an N2 atmosphere at 100 deg.C for sixty hours. The oxygen in the neighborhood of the surface of the wafer 1 and the impurities, which are united with the oxygen, are diffused to outside, and a defectless region 2 having no microscopic defects is formed. By the manufacture of an IGBT using the wafer 1 which has a defectless region 2 on both sides as above-mentioned, the IGBT having withstand voltage of excellent characteristics of 2500V or higher can be obtained, because the dislocation of the intermediate part and the defect such as stack fault and the like are dcreased by moving the intermediate part to the defectless region by heating in the process. In order to accomplish the above-mentioned result, oxygen concentration of 1017/cm3 or higher is required.
